Disadvantages of high-carbon diet, in real life, there are many kinds of foods, and our common foods also contain carbohydrates, but such high-carbon foods are generally not allowed to eat more. Let's share with you the disadvantages of a high-carbon diet.
Disadvantages of high-carbon diet 1 high-carbon water diet will bring insulin resistance: high-carbon water food will cause violent fluctuations in blood sugar, which will make the pancreas have to work overtime, and the body will be in a state of secreting a lot of insulin for a long time, which will easily lead to the insensitivity of cells in the body to insulin, that is, insulin resistance, which will keep blood sugar high and even lead to diabetes.
Insulin resistance leads to endocrine disorders: Insulin resistance is not a patent for diabetic patients. Polycystic ovary syndrome (PCOS), a disease related to female endocrine, is often accompanied by insulin resistance. 50-75% patients with polycystic ovary syndrome have different degrees of insulin resistance, and the risk of developing type II diabetes is 5- 10 times that of normal women.
Precautions:
In addition to carbohydrates, it also contains a lot of protein provided by plants, and it is worth mentioning that the fat content is not much.
This kind of noodles is similar to bread. Generally speaking, noodles are usually eaten with vegetables and meat. Because their digestion and absorption are relatively slow, it is recommended to eat pasta and other foods before exercise. Fruits also contain carbohydrates, but there are fewer carbohydrates in fruits, which mainly provide vitamins and minerals.
Disadvantages of high-carbon diet 2 First of all, let's understand what carbohydrates are.
Carbohydrates, also known as glycogen compounds, are mainly composed of three elements: carbon, hydrogen and oxygen. They are the cheapest nutrients for human body to provide heat energy and the most abundant and widely distributed key organic compounds in nature. From the point of view of nutrition, there are mainly two kinds of carbohydrates: "good" carbohydrates and "bad" carbohydrates.
So, what will be the impact of a high-carbon water diet?
1, high-carbon water diet, will bring insulin resistance: high-carbon water food, will cause violent fluctuations in blood sugar, so that the pancreas has to "work overtime", the body is in a state of secreting a lot of insulin for a long time, which will easily lead to the insensitivity of cells in the body to insulin, that is, insulin resistance, which will keep blood sugar high and even lead to diabetes. Insulin is an important hormone in glucose metabolism.
Because only with the help of insulin can the sugar in the blood enter every cell smoothly and become the energy source of cells. Insulin resistance will hinder this process, making cells unable to eat sugar and weak due to lack of energy.
Insulin resistance also means that the body is in an inflammatory state. Therefore, many people who don't leave white rice, white flour and sugary drinks every day often feel tired, sleepy and irritable; Those who have allergic symptoms are also prone to allergic attacks after eating a lot of sugar. Many people are eager to decompress through sugary foods such as desserts when they are stressed and depressed, which is also related to the special role of sugar in the human body.
2, high-carbon water diet, causing obesity: the purity of special sugar in carbohydrates is very high, which can reach more than 99%, which means that there are basically no other nutrients, only a lot of kinetic energy.
If you eat too many sweets, people will feel full because of too much kinetic energy, which will further affect the intake of other foods containing protein, vitamins, minerals, dietary fiber and so on. Excessive sugar will also be converted into body fat, which will affect all normal appetites, hinder the intake of vitamins, minerals and other nutrients, and lead to obesity.
3, high-carbon water diet, leading to three high diseases: for middle-aged women, it is even more necessary to eat less carbohydrates (desserts) to prevent high blood sugar concentration, leading to hyperlipidemia, arteriosclerosis, obesity, hypertension, coronary heart disease, diabetes, osteoporosis, seriously endangering physical and mental health. British scientists have found that women over 50 eat too many sweets, which can lead to gallstones.
4, high-carbon water diet, very easy to get breast cancer: eating more carbohydrates (glycogen) can also contribute to the more common incidence of breast cancer. According to scientific research, long-term intake of high-sugar and high-calorie food can keep insulin glargine in the blood in a high quality state, and breast tumor cells need a lot of insulin glargine in their early growth and development. Insulin glargine is digested and absorbed by many breasts, which is helpful for the growth, development and reproduction of breast tumor cells.
5, high-carbon water diet, very easy to decline: eating more carbohydrates (glycogen) will continue to accelerate the embrittlement of somatic cells, making the human body's natural environment adaptability poor, hair turning yellow and skin turning white. When sugar is left in the mouth, bacteria will multiply and produce some citric acid and enzymes, which will immediately destroy teeth, decalcify teeth and produce dental caries. Therefore, middle-aged and elderly women are not suitable for eating more sweets.
6, high-carbon water diet, easy to fracture: eat more carbohydrates (sugar), so that human metabolism needs to consume a variety of vitamins and minerals, therefore, eating sugar often will cause nutritional problems such as vitamin deficiency, calcium deficiency, potassium deficiency. Japanese nutritionists believe that children's excessive intake of carbohydrates (sweets) is an important reason for the increase in fracture rate; American nutritionists also pointed out that children who love sweets have a higher fracture rate.
7, high-carbon water diet, induce chronic diseases: Although eating sugar may not directly lead to diabetes, but eating sweets for a long time will make carbohydrate and fat metabolism disorder, cause imbalance in the human body's internal environment, and then promote a variety of chronic diseases, such as cardiovascular and cerebrovascular diseases, diabetes, obesity, senile cataracts, dental caries, myopia, rickets and so on. Eating more sweets will also make human blood tend to be acidic, which is not conducive to blood circulation and weakens the defense function of the immune system.
How to correctly ingest carbohydrates?
1, according to the potential disease risk: according to different physical needs, it is particularly important to match reasonable eating habits. Obesity, hyperglycemia, metabolic syndrome and diabetes (1 type and type 2) should pay special attention to diet balance and should consume very low carbohydrates; During weight loss, adjust digestive function, suitable for low carbohydrate; When maintaining weight and relieving adrenal fatigue, we should take in proper amount of carbohydrates. Professional athletes, or people who want to gain weight, are suitable for high carbohydrate.
2. Make a schedule: Not every carbohydrate is suitable for everyone. You can make a good health schedule, record your calories and choose the right ingredients.
3, pregnant women need to pay attention: pregnant women must absorb a lot of carbohydrates to maintain the' nutritional supplement' of the fetus and mother. If the intake is insufficient, it will easily lead to low blood sugar level, which will affect the health of the fetus and mother. The easiest and quickest way for pregnant women to replenish energy quickly is to eat steamed bread or rice and supplement carbohydrates.
Disadvantages of high-carbon diet 3 Too much sugar intake will make you stupid.
Although there is no word "being stupid" in medicine, when we generally talk about being stupid, we mean memory loss, forgetfulness, carelessness, inability to complete things that could have been done easily before, and so on. In fact, these are all related to the cognitive function of the brain.
The cognitive function of the brain is divided into many elements, besides memory, it also includes the ability of rational thinking, both of which are related to the frontal lobe. Excessive intake of unhealthy sugar will reduce the activity of the frontal lobe. Although there is nothing unusual at first, the workload that can be handled will indeed decrease gradually.
Relationship between sugar, body weight and cognitive function
During the period of 2065438+2008, university of basel observed three groups of healthy adults with an average age of 24.8 years. The research team injected them with 300 ml of liquid using a nasogastric tube. 1 group, water contains 75g of glucose, the second group contains 25g of fructose, and the third group is pure boiled water. After filling it out, let them have an MRI and start a cognitive function test. Results There was no significant difference in cognitive function scores among the three groups, but MRI showed that the activities of anterior cingulate gyrus and posterior prefrontal cortex, which dealt with working memory and inhibitory response, were significantly reduced in the two groups.
The research team said that working memory means that the brain temporarily stores some information and analyzes it, such as remembering phone numbers. The inhibition reaction includes inhibiting unnecessary or inappropriate actions, such as undressing outside or stopping after scratching, but glucose and fructose will reduce these two abilities of the brain.
From 2065438 to February 2009, a retrospective study investigated the relationship between sugar, weight and cognitive function in 10 years, and found that fast intake of high-calorie and high-sugar foods can cause cognitive impairment, especially in the hippocampus, which will lead to inability to remember new things, low scores in short-term memory tests, or always forgetting the details and processes of things.
Too much free sugar can inhibit the brain nerves.
However, such research is inconsistent with the concept that the brain needs glucose for energy supply. 2065438+In July 2009, a study in Kebangsaan, Malaysia explained this point. These harmful sugar sources are mainly free sugar, that is, sugar added to desserts, drinks and cakes, sugar from food additives or refined sugar.
It is found that excessive free sugar can inhibit the synaptic development of the brain, lead to cognitive defects, and also reduce the concentration of brain-derived neurotrophic factor (BDNF), thus reducing the performance of memory and cognitive function.
But relatively speaking, carbohydrates such as whole grains contain different nutrients such as sugar, protein, vitamins and minerals, and the digestion process is slow and complicated, which offsets the harm caused by high sugar. Even so, it is just right.
